Hi all
i just wonder about the general gas prices in US ... is they differ from state to state? and how many $ you pay for its liter or galon...
and i wonder also is 3800 engines are overally fuel efficient or what?what do you think about their fuel consumption..? i just wanna learn this situation..also i heard that multi port injection is good about both its performance and economy...can you open this statement little bit? thanks again....

its 2.28 a gallon here in ohio

using 91 octane (premium, not super premium) its $2.38 here in southern ct

it's around 2.40 for regular

$1.94 for 89.5 here in central Iowa

lol. here in the windy city from $2.50 to $2.95
ya crazy

3800's are very fuel efficient - for thier class of engine. Its no 4 cyl by any means, but for the amount of power you get vs. how far you can drive on a tank, the 3800 is a very balanced engine. One of GM's better projects!

Gas is around $2.20 in South Central Pennsylvania. Heh, I know my GM 3.8 V6 doesen't get good gas milage, I can fill up on a tank, drive a couple of hours and have to fill up again, although I drive 70-80MPH everywhere.

that's probably why

yeah as we say balanced can we say this situation for other straigt L6 engines of GM? i dont remember where i read but i read it somewhere these V6 (our engines) performs better than GM's straight L6 engine designs...is this true? because in late thunderbirds and some 90's firebirds are equipeed with supercharged versions of 3800 V6 ? i hope i am not wrong?

well the 3800 has been around in one revision or another now since 1987... 3.8L since even earlier. But a good design never goes out of style!

I know there are many supercharged versions of this engine aswell! They still produce many vehicles with the supercharged version of the 3800. I am not sure about thunderbirds, but I know firebirds were quite commonly equipped with 3800's.

Hi oldsman83, hello all,


$1.37 per gallon yesterday in the Los Angeles area. That includes $.55 in taxes.


TBI and Multi port are improvements over a carb. Sequential and tuned port are much more efficient.


If all other factors are equal, there will be no difference. The reason for the V6 configuration, was to fit it into a smaller space.


Tbird uses a Ford engine, the size is a coincidence, no parts will interchange.

Olds used the GM "Corporate" Buick engine. Buick and Pontiac still do.


231 cubic inch V6 was introduced in 1961 as the base engine in the Buick Special/Skylark. 3800/3.8 would still be a 231 if the US had not converted to the metric system.

Buick 231 to 3800 evolution is similar to the "Corporate" Chev 350 to 5.7 (5700?). The design was improved over the years in both.
